Link for creeper chains



6, MARZO I LINK FOR CREEPER CHAINS Filed May 23, 1967 FIG-1 FIG-2INVENTOR BY 4 F1063 ATTORNEY United States Patent LINK FOR CREEPERCHAINS Victor Milian Marzo, Chirivella, Valencia, Spain, assignor toIndustrias Yuk, S.L., Chirivella, Spain, a corporation of Spain FiledMay 23, 1967, Ser. No. 640,678 Claims priority, application Spain, June14, 1966, 122,609 Int. Cl. F16g 13/06 US. Cl. 59-90 3 Claims ABSTRACT OFTHE DISCLOSURE The links for bottle creeper chains which are known atpresent are made up by means of a flatbar from whose opposite edgesthere project curved fins which act as setting hinges between links.This type of chain sufiers from serious problems because those curvedfins which act as setting hinges during its work tend to unfold, withthe resulting uncoupling of the links which make up the chains.

The patent of invention which is applied for solves those problems bymeans of a simple and economical organisation. Its aim is to see thatthe curved fins of the links cannot unfold during the working of thechain, thus preventing the uncoupling between links.

For this purpose, the link for creeper chains which is applied for ischaracterised because, being of the type which is made up by means of aflatbar from whose opposite edges there project curved fins which act assetting hinges between links, it presents said fins anchored on theflatbar itself which makes up the link, so that on the end of each finopposite that on which it is joined to the edge of the flatbar, itpasses through the body of the latter, remaining substantially rivetedon same.

A page of drawings has been drawn up by way of explanation and withoutany restrictive nature whatsoever, in order to aid the comprehension ofthe idea stated. It illustrates this specification as an example ofembodiment of the object with which we are concerned.

FIGURE 1 otters us a bottom view of the link with which we areconcerned. As can be seen, it is of the type which is made up by meansof a flatbar 1 from Whose opposite edges there project curved fins 2which act as setting hinges between links.

FIG. 2 is a vertical cross sectional view taken through line 2-2 of FIG.1 and looking in the direction of the arrows.

Now then, a real innovation is established by the fact that said fins 2are anchored on the flatbar 1 itself which makes up the link so that theend of each fin 2 opposite that on which it is joined to the edge of theflatbar passes through the body of the latter, remaining substantiallyriveted on same.

For this, the ends of the mentioned fins 2 are provided with extensions3, which are precisely those which pass through the flatbar 1 itself,which has windows 4 for this purpose.

FIGURE 2 otters us a cross section of the link. As can be seen, theflatbar 1 presents curved fins 2 which act as setting hinges betweenlinks. Observe that the end of each fin opposite that on which it isjoined to the edge of the flatbar 1 passes through the body of thelatter, remaining substantially riveted on same by 5.

In the industrial sphere, the embodiment described offers a decisiveseries of advantages. In fact, the fact of anchoring the fins on theflatbar itself in such a way that their ends pass through the body ofthe latter is due to a simplified manufacturing process which does notincrease the habitual production costs and which allows one to expendthese tools on the market at attainable prices.

If we also consider the fact that said embodiment prevents uncouplingbetween links, as the fins always remain in the same position, it isevident that the patent of invention applied for acquires a singularpractical utility because of the new benefit or effect which itcontributes to the function for which it is designed.

In short, the patent of invention which is applied for will correspondto the following claims.

I claim:

1. A link for an articulated chain comprising:

a flat bar including opposed edges,

each of said edges including a reverse-bend portion forming an integralhinge-sleeve at one side of said bar for connection to another link of achain,

said reverse-bend portions including a terminal end portion connected tosaid bar,

said bar including a portion forming an aperture spaced inwardly of saidedges,

said terminal end portions of said sleeve extending through a respectiveaperture and being fixedly secured therein.

2. The structure as claimed in claim 1 in which the terminal endportions of said sleeves are enlarged in said lrjespective apertures tointegrally rivet said sleeves to said 3. The structure as claimed inclaim 1 in which said link includes two sleeves extending from one edgeof said bar, and one linkextending from the other edge of said bar, saidtwo sleeves being spaced from each other a distance sufiicient toreceive between.
